am I the only one who didn't already know this?

I heard in a radio interview today that two of the D!x!e Ch!cks struggled with infertility (both now have twins) and wrote the song So Hard about the experience. How did I not know that? I love the DCs, and actually own the cd the song is on, but I guess I never listened closely to that track. As soon as I got home I put the disc on and it is plain as day.
